SPINDLE.

Specification of Letters Patent.

Application filed August 19, 1907.

Patented May 25, 1909.

Serial No. 389,285.

T 0 all whom it may concern:

Be it known that I, JOSEPH N. KnLsnA, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Spindles, of

which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in spindles especially designed for winding silk and the objects of the invention are to provide a spindle that may be weighted to suit the use of silk of varying degrees of strength by adding to or taking away one or more of the units of weight which form an essential part of the head of the spindle and to pro vide the head of the spindle with a contact surface or sleeve to be engaged by friction with a driving-pulley that will be less apt to wear because of such friction and will prolong the life of the spindle.

The invention consists in the combination, with the spindle proper, of an enlarged portion or head comprising removable washers, the outer ones being of wood or some other light material and the intermediate ones being of metal or other heavy weighting material, and a sleeve or covering of vulcanized fiber inclosing said washers, and forming a contact surface for frictional engagement with the means for driving the spindle.

The weighting units may consist of metal washers immediately encircling the spindle proper, or may consist of one or more washers of wood or other suitable material provided with a circumferential groove filled with metal or other weighting material as shown in the drawings accompanying and forming a part of this specification.

It is obvious that in practice many combinations of my removable units may be made with my friction sleeve of vulcanized fiber and the spindle of which the sleeve and units form the head.

In Figure 1 is shown a complete spindle; and in Figs. 2, 3 and 4 are shown vertical sections illustrating the method of building up the head of the spindle by different combinations of removable units.

Fig. 2 shows a shell, secured to the spindle, containing three weight units or washers encircling the spindle, a top washer of wood or other light material which serves as a cover,

I and surrounding the whole a vulcanized fiber sleeve.

Fig. 3 shows top and bottom wooden washers encircling the spindle and provided with a circumferential groove adapted to receive a ring orwasher of heavier material, intermediate metal washers, likewise encircling the spindle, and the vulcanized fiber sleeve inclosing all said removable units.

Fig. 4 shows four wooden washers or units, each having a circumferential groove to receive weighting material, and the weighting material in said grooves, said grooved washers immediately encircling the spindle, and the sleeve of vulcanized fiber inclosing said units, and forming a contact surface adapted to be frictionally engaged by means of driving the spindle.

In the drawings the spindle 1- is provided with the usual spring 1" to hold a bobbin thereon, -2- represents the vulcanized fiber sleeve, 3 a shell, 3 a removable wooden washer or cover for shell, 4 removable weight units and 5-- washers or removable units having circumferential grooves.

The size of the wooden washer and its circumferential groove may be varied and one or many may be used at pleasure without departing from the scope and spirit of my invention and I do not wish to limit myself in reference th ereto.

1. The combinationwith the spindle pro er of a head secured thereto comprising a p urality of removable units of weighting material, means for holding said removable units and a vulcanized fiber sleeve inclosing the same, and forming a contact surface for frictional engagement for driving purposes substantially as set forth.

2. The combination with a spindle, of a washer having a circumferential groove around the same, weighting material carried in said groove and a friction sleeve inclosing said washer, and forming a contact surface for frictional engagement by the driving means substantially as set forth.

3. The combination with a spindle, of a washer, having a circumferential groove, immediately encircling the same, weighting material carried in said groove and a vulcanized fiber friction sleeve inclosing said washer and forming a contact surface adapted to be frictionally engaged for driving purposes In testimony whereof I aflix my signature substentially aslset fkorth. 4 1 in presence of two witnesses.

4. in a spind e, t e combination Wits. the spindle propel, ofa circumferentially grooved JOSEPH KELSEA' 5 Washer immediately encircling the same and Witnesses:

Weighting material carried in said groove, CHARLES FROST, substantially as set forth. 1 4 JOHN F. KERR.
